To'all whom it may concern.: y

Be it known that l, EDWARD HAsKiNs SnAoKELronn, a citizen of the United States, residing at Salt Lake City, in the countyof Salt Lake and State of Utah, have invented a new andv useful Improvement in Box- Cleaning Devices lfor Concentrating Tables, of which the following is a specification.

This invention is a cleaning device lor the outlet boxes )f vanners, lViltley tables and all other kinds of concentrating tables which have a shakingframe or' table discharging` into a concentrate box at' the end oi the inachine..

The concentrates when discharged into the box, tend to settle to the bottom thereof in a tighter dense mass, and it is the object. of this invention to provide means to keep the concentrates continuously stirred up or in motion andto move them slowly and gradually tothe outlet or discharge pipe, which, with the'l'low of water supplied to such tables will act to discharge the values through the The invention is illustrated in the accompanying drawings, in which Figure l is an end elevation, partly in section, of a vanncr with the. invention ap- Fig. 2 is a partial side elevation thereof, partly in section. Figs. 3 and ft are details in plan and side view of one type of rack. Figs. 5, 6 and 7 are details in plan, side view and section of another type. Figs. S, 9 and l() are similar views of still another type. Figs. l l., 12 and 13 are details of a device ior dischargmg air or water for the same purpose as the racks referred to.

ln thedrawings, only so much. ol' a vanner is illustrated as is necessary to show my invention. 'lhe vanner belt l0 travels at its discharge end around rollers ll. and l2 (supported by the frame 13) and through the V-shaped concentratebox 14. The frame and belt have the well known lateral vibration or movement imparted by means which need not beshown or described here, and the concentrates arc discharged or Washed from the belt into the box by the constant lloWor supply ot water.

The concentrates tend to pack or scttlc in the box, andto avoid this l. provide a rack suspended from the shaking frame by hangers l5 at the ends of the rack, so that the rack has longitudinal vibration according to that of the belt and frame. The outlet pipeat thc end of the box is indicated at 16, with a wooden plug 17 and porcelain bushing 18, andlthe concentrates are discharged through this pipe.

Therack maybe made in various forms and material. In Figs. l to 4 inclusive l show a wooden rack consisting of a bar l?) the bottoni and opposite sides of which are notched or stepped as indicated at 20, with inclincs and square shoulde; s. the latter be inol )resented toward the outlet;

l hen the rack bar is vibrated it acts in consequence of its form to cause a i'ioWlof Water and feed .ol`concentrates lengtlnvise in the box toward the outlet and keeps the water in motion and the concentrates continually stirred up, so that the),r do not pack, but are Washed. out through the hole in the outlet pipe.

` In the type of rack shown in Figs. 5, (3 and 7 a bar 21 is provided having square 'shouldered notches in its lower edge and side plates 22 at each side. The action is the same as ,above described.

In the type shown in Figs. 8, 9 and l0, a bar 23, preferably metal, is provided with depending swinging plates 24 which on the forward stroke, stop against tht` bar in perpendicular position and on the backward stroke swing to inclined position as shown in dotted lilies Fig. 9. The action istosweep or lorce the water and values toward the outlet.

ln Figs. 1l, l2 and 13, l show a. niodilication in structure and operation, comprising a pipe 25 suspended by the hangers and supplied with water or air through a flexible hose 26. Said pipe has holes or slits 27 cut or struck in, in such manner that the iluidis discharged downwardly and forwardly at an angle toward thc bottom ol' the box. And its ell'ect on the lconcentrates is similar to that above described, the flow or lorcc ol the lluid acting to agitato the concentrates and force them toward theoutlet.

Various other inodilications of ,the invention may be made or employed within the scope thereof.

I claim 1. The combination with a concentrate box having an outlet for the concentrates, and a vibrating frame carrying concentrating devices which 'discharge into said box, of means carried by theframe and vibrated thereby to positively impel the concentrates in the box toward theoutlct.

2. The combination with a vibrating concentrating device, and a concentrate box into which it discharges, said box having an out- Wise in said box and connected to and vi- 10 let, of means carried by the'said device and brating with the concentrating device and vibrating therewith to agitatol the material constructed to agitate the material in the box in the box and positively impel the concenand positively impelit toward the outlet.
